Sally Sutton argues people would go to the Easter carnival even without jumps.

Opponents of jumps racing hope its likely demise at Adelaide's main racecourse, Morphettville, will pave the way for a statewide ban in South Australia.

The South Australian Jockey Club (SAJC) said its course revenue and image were being adversely affected by staging jumps events.

The Adelaide jumps season is ending at Morphettville this weekend and the SAJC is keen not to hold any future jumps events at the city racecourse.

Sally Sutton, of the Coalition for the Protection of Racehorses, believes the SAJC decision reflects a wider community opposition to jumps events, which she argues are cruel to horses.

She is urging the SA Government to act against allowing jumps racing anywhere in the state, including at the popular Easter racing carnival at Oakbank in the Adelaide Hills.

"We believe that people would still attend the Oakbank carnival whether there were jumps there or not," she said.

"Most people who go to Oakbank aren't going for the jumps racing, they're going for the spectacle, it's a family day.

"Oakbank doesn't rely on jumps racing, it's time that it ended there."

But the Oakbank racing organisers say they need city jumps events to help attract interstate horses and trainers to their Easter carnival and they think the SAJC is ignoring the wider health of the racing industry.

The SAJC chief executive Brenton Wilkinson has said the club wants to move away from hosting jumps racing as it is affecting the club's brand and business.

It's not acceptable in 2014 to have such an event called a sport and accepted by the community.

The jockey club said some people had boycotted hiring its function facilities and it wanted to protect and enhance its revenue across the entire year.

But a final decision on the future for jumps rests with Thoroughbred Racing SA, which has indicated it remains committed to such racing.

It plans to meet the SAJC in October to discuss the way forward for jumps.

Victorian owner Pearse Morgan lost one of his horses in a race earlier in the year but insists safety standards are first class.

"It's very sad when they pass away but we all love our jumpers, they love jumping," he said.

"As an owner of jumpers I just hope that they don't go through with that decision and continue with jumps racing here because it's a great spectacle, a great sport and it brings people to the races."

South Australian Greens MLC Tammy Franks is backing the view of animal rights activists that jumps events are cruel and dangerous.

"We know that we see the 'green screen of death' come up at jumps races far too often," she said.

"It's not acceptable in 2014 to have such an event called a sport and accepted by the community.

"I think the community has spoken and fortunately this time the SAJC has listened."

SA and Victoria are the only states where jumps events are still held.

The RSPCA said clear figures on the number of jumps-related deaths were hard to compile.

It said more than a dozen horses had died or been put down at South Australian racetracks in the past five years but the number of deaths might be much higher because deaths in race trials were not formally added to the tally.

The animal welfare organisation said research over more than a decade had shown the risk of a horse dying during jumps racing was almost 19 times higher than for races on the flat.
